3. Persediaan
3.1 Battery Installation and Activation
The Magene S3+ sensor comes with a pre-installed CR2032 battery. Before first use, you must remove the insulating sheet from the battery compartment. Open the sensor cover by twisting it counter-clockwise, remove the plastic sheet, and then close the cover by twisting clockwise until secure.
3.2 Mode Switching (Speed or Cadence)
The S3+ sensor operates in one mode at a time: either speed or cadence. To switch between modes, you need to reinstall the battery. The sensor's LED indicator will flash to confirm the selected mode:
- Green Indicator Flash: Sensor is in Speed Mode.
- Red Indicator Flash: Sensor is in Cadence Mode.
After switching modes, it is necessary to reconnect the device to your cycling computer or application to display the new mode's data correctly.

3.3 Pemasangan
Choose the appropriate installation method based on your desired measurement mode:
For Speed Measurement:
- Ensure the sensor is in Speed Mode (Green LED flash).
- Attach the sensor to the hub of your front or rear wheel using the large rubber elastic ring. Ensure it is securely fastened and does not interfere with any moving parts.
For Cadence Measurement:
- Ensure the sensor is in Cadence Mode (Red LED flash).
- Attach the sensor to the inside of your bicycle's crank arm using the small rubber elastic ring. Position it so it does not interfere with pedaling or other components.
4. Arahan Operasi
4.1 Berpasangan dengan Peranti
The Magene S3+ sensor supports both ANT+ and Bluetooth 4.0 for connectivity.
- Untuk Sambungan Bluetooth: When connecting to a smartphone application, you must search for the sensor directly within the app. Searching through the phone's system Bluetooth settings will not establish a valid connection. A single Bluetooth sensor can connect to only one application or device at a time.
- For ANT+ Connection: The sensor can be connected to multiple ANT+ compatible devices simultaneously, such as cycling computers and smartwatches.

4.2 Mod Tidur Automatik
To conserve battery life, the S3+ sensor will automatically enter a sleep state after 1 minute of inactivity. The sensor will only begin transmitting data again once it is properly reactivated by movement (e.g., rotating the wheel or crank arm).
5. Penyelenggaraan
5.1 Penggantian Bateri
The sensor uses a CR2032 lithium coin cell battery. When the battery is low, the LED indicator may not flash or may appear dim. To replace the battery:
- Twist the sensor cover counter-clockwise to open the battery compartment.
- Keluarkan bateri CR2032 lama dengan berhati-hati.
- Masukkan bateri CR2032 baharu dengan bahagian positif (+) menghadap ke atas.
- Close the cover by twisting clockwise until it is securely sealed. Ensure the rubber gasket is properly seated to maintain water resistance.
Remember that reinstalling the battery will also trigger the mode switching sequence (Speed or Cadence), so verify your desired mode after replacement.
5.2 Cleaning and Water Resistance
The Magene S3+ sensor has an IP66 waterproof rating, meaning it is protected against powerful water jets. It is suitable for use in rainy conditions. However, it is not designed for prolonged submersion or high-pressure cleaning. To clean the sensor, wipe it with a damp kain. Elakkan menggunakan bahan kimia yang keras atau bahan yang melelas.

6. Penyelesaian masalah
- Sensor not detected by device/app:
- Ensure the battery insulation sheet has been removed and the battery is correctly installed.
- Wake up the sensor by rotating the wheel or crank arm.
- For Bluetooth connections, search for the sensor within the app itself, not through your phone's system Bluetooth settings.
- Check if the sensor is already connected to another device (especially for Bluetooth, which supports only one connection at a time).
- Replace the battery if it is low or depleted.
- Incorrect speed/cadence readings:
- Verify that the sensor is in the correct mode (Speed or Cadence) as indicated by the LED flash during battery reinstallation.
- Ensure the sensor is securely mounted and not shifting during activity.
- For speed mode, ensure your cycling computer or app has the correct wheel circumference set.
- Sensor not waking up from sleep mode:
- Ensure the sensor is subjected to sufficient movement (e.g., several rotations of the wheel or crank arm) to activate it.
- Periksa tahap bateri dan ganti jika perlu.
